How to tell if your iPhone is water damaged?

I was dying my hair with kool aid when the bowl tipped over NEAR my iPhone. It was in a speck case and a couple drops got on the screen and maybe in the headphone hole and charger plug. The phone worked fine but told me there were headphones in when there weren't and whenever i made calls i couldnt hear the other person. I put the phone in rice to absorb the liquid but then rice got stuck in the headphone hole! I got pretty much all of the rice out but it had absorbed a lot of the kool aid. How do i tell if the phone is ruined?

If it doesn't work, it is ruined. By definition, that's what it means.

You can tell if it has any damages, if not don't worry dawg
